Expression -- Description ? help Back to Top
Source Description
UniprotDEVELOPMENTAL STAGE: Expressed during plant development. During pollen development, required for crosporogenesis that leads to archesporial formation and for the histogenesis of the microsporangia. During ovules development, involved in the transition to meiosis of the megaspore mother cells. {ECO:0000269|PubMed:10524240, ECO:0000269|PubMed:12671094}.
UniprotTISSUE SPECIFICITY: Expressed in shoot apical region and early floral tissues. Transcripts levels increase in developing pollen sacs, and decrease in later stage of anther development. Strongly expressed in the placental region of the carpels. {ECO:0000269|PubMed:12671094, ECO:0000269|PubMed:17093870}.
Functional Description ? help Back to Top
Source Description
UniProtTrans-acting factor that binds specifically to the consensus nucleotide sequence 5'-TNCGTACAA-3'. Binds specifically to the 5'-GTAC-3' core sequence. Involved in development and floral organogenesis. Required for ovule differentiation, pollen production, filament elongation, seed formation and siliques elongation. Also seems to play a role in the formation of trichomes on sepals. May positively modulate gibberellin (GA) signaling in flower. {ECO:0000269|PubMed:12671094, ECO:0000269|PubMed:16095614, ECO:0000269|PubMed:17093870}.
